Thomas Amo. An Apple for Zoë. Book I, The Forsaken (2011) 309 pp. [tpo]
Publishers description: The City of San Francisco is locked in a grip of fear. A series of occult murders has led, Inspector Thomas James, to a crime scene similar to a murder committed 90 years ago in the once grand Aleris Hotel. A place where power barons of the early 20th century engaged in witchcraft. And silent film stars indulged in the most wicked of sins. A place where no one questions the black smoke that rises from the hotels incinerators in the middle of the night.
Setting: San Francisco
